+
+_retrieve the sourcecode for a method_
+
+*NOTE:* This simply utilizes `Method#source_location`; it
+ does not access the live AST.
+
+`method_source` is a utility to return a method's sourcecode as a
+Ruby string. Also returns `Proc` and `Lambda` sourcecode.
+
+Method comments can also be extracted using the `comment` method.
+
+It is written in pure Ruby (no C).
+
+* Some Ruby 1.8 support now available.
+* Support for MRI, RBX, JRuby, REE
+
+`method_source` provides the `source` and `comment` methods to the `Method` and
+`UnboundMethod` and `Proc` classes.
+
+* Install the [gem](https://rubygems.org/gems/method_source): `gem install method_source`
+* Read the [documentation](https://www.rubydoc.info/github/banister/method_source/master)
+* See the [source code](http://github.com/banister/method_source)
+
+Example: display method source
+------------------------------
+
+    Set.instance_method(:merge).source.display
+    # =>
+    def merge(enum)
+      if enum.instance_of?(self.class)
+        @hash.update(enum.instance_variable_get(:@hash))
+      else
+        do_with_enum(enum) { |o| add(o) }
+      end
+
+      self
+    end
+
+Example: display method comments
+--------------------------------
+
+    Set.instance_method(:merge).comment.display
+    # =>
+    # Merges the elements of the given enumerable object to the set and
+    # returns self.
+
+Example: display module/class comments
+--------------------------------------
+
+    MethodSource::MethodExtensions.method(:included).module_comment
+    # =>
+    # This module is to be included by `Method` and `UnboundMethod` and
+    # provides the `#source` functionality
+
+Limitations:
+------------
+
+* Occasional strange behaviour in Ruby 1.8
+* Cannot return source for C methods.
+* Cannot return source for dynamically defined methods.
+
+Special Thanks
+--------------
+
+[Adam Sanderson](https://github.com/adamsanderson) for `comment` functionality.

+[Dmitry Elastic](https://github.com/dmitryelastic) for the brilliant Ruby 1.8 `source_location` hack.
